Systemic Safety
Projects

Executive Manager NJDOT

CLRS across the Nation and in NJ
 CLRS create noise & vibration inside your vehicle
that alert you as you cross the center line.
 11 state and one national study show that CLRS
reduces crossover crashes 18 to 64%.
 NJDOT had a systematic program for CLRS from
2014 thru 2015.
 All paving projects currently include CLRS on two
lane and multilane undivided highways.

Crash Data
Three Roadway Departure (RwD) Emphasis Areas
make up 75% of RwD crashes. CLRS helps reduce all
of them:
 Head-on crashes
 Rollover
 Trees

Criteria
 Centerline rumble strips are constructed at the
yellow centerline stripe, both passing & no
passing zones.
 Rural & urban 2-Lane roads & multilane undivided
highways
 Posted speed limits of 35 MPH or higher
 10 foot minimum lane width (was 11 feet)
 HMA pavement must be in good condition with a
surface distress index (SDI) greater than 3

Criteria
Centerline rumble strips shall not be constructed at
the following locations:
 Street intersections: Construct to the end of
centerline stripe.
 Along left turn slots and continuous two-way left-
turn median lanes
 Bridge decks or concrete bridge approach slabs.
 Concrete pavement
 200 feet before and after the approximate mid-
point of Weigh-in-Motion (WIM) systems in the
roadway

Fog seal surface treatment shall be
applied after construction of the
CLRS

9. DO NOT CONSTRUCT RUMBLE STRIPS 200’ BEFORE & AFTER THE
APPROX. MIDPOINT OF W.I.M. SYSTEMS IN THE ROADWAY

CLRS Program Progress to Date
 ~497 miles of CLRS installed systemically in Federal
FY 2014.
 ~270 miles of CLRS installed systemically in Federal
FY 2015.
 All paving projects currently include centerline
rumble strips on two lane and multilane undivided
highways.

HIGH FRICTION SURFACE
TREATMENT
(HFST)
MADE EASY

What is a
High Friction Surface Treatment?
• High Friction Surface Treatments (HFST) are
pavement surfacing overlay systems with:
 exceptional skid-resistant properties that are not
typically acquired by conventional materials
 retains the higher friction property for a much
longer time.
• Commercially available resin-based products
• Generally applied in short sections to improve safety
in spot locations where friction demand is critical.

HFST Binder Materials
• Polymer binder systems
• Epoxy-resin two-part systems
• Polyester-resin three part systems
• A laminate layer
that allows for
75% aggregate
embedment depth

HFST Aggregates
• Recommended aggregate is calcined bauxite
which is highly durable & provides the highest
resistance to polishing.

Decel. Rate = 10 ft./s2
d = 1.075 (V2 / 10 ft./s2)
V = MPH
Solve for d for V1 (Posted Speed). Then solve for d for
V2 (curve speed), Subtract V1 – V2 to get upstream
distance, or use chart below:

Things to consider for HFST use.
• Is safe speed on curve less than or equal to
posted speed. If yes, consider superelevating
curve and /or adding shoulder if practical. Added
shoulders and chevrons can attain a 70%
reduction in run off the road crashes (Illinois
DOT). Also place advisory speed signs.
• Chevrons can attain a 30 to 40% reduction in
crashes (Illinois DOT).
• When applying on ramps, upgrade signing
(advisory speed, chevrons, etc) and striping as
per current MUTCD).

Things to consider for HFST use.
• Clear fixed objects from clear zone such as trees.
50% of run off the road accidents involve a tree.
Trees are involved in 8 to 11 fatalities a day.
That’s 1 fatality every 2 to 3 hours in the US.
• Apply HFST on new pavement up to
approximately 3 years old. Condition rating > 3.2.
• Two applications needed for concrete bridge
decks and open graded friction course.

Weather to Apply HFST
• Min. Surface Temp.: 55 degrees
• Max. Ambient Temp.: 105 degrees
• May thru August construction
• Do not place HFST, if within 3 hours of HFST,
the National Weather Service locally forecasts
a 40 percent chance, or greater, of rain.

HFST is a great safety treatment
that happens to be a pavement!

• Utility Risk “Drivers”
Frequent causes of adverse
impacts
• Utility Risk Considerations
• Utility “Tools”
To support the Design and
Construction Phases

Utility Risk - Drivers
Transportation Agencies & Design
Consultants…Utility related “Risk Drivers”
 Utilities - Have least control over one of
the more critical design components
 Selection of Design Team by choice,
Utility Team members are given
 Proximity of Work Environment….
 Highway, Traffic, Survey,
Structures,….”under one roof”
 Utilities, electric, gas, communications,
water, sanitary, etc. ….”off premises”

Utility Company….. “Risk Drivers”
 Utility Companies have their own
established Requirements &
Criteria
 Have Limited & Specialized
Resources
 Utility Customer Demands and
unanticipated emergencies
 Specialized Technical Utility
Expertise

Utility Company…..

Utility Risk - Considerations
Approach…..
Incorporate Utility work in the highway
construction contract
Risk Consideration…..
Utility work in the highway construction
contract is an excellent approach…. however,
the required utility construction staging must
be properly integrated.

Approach…..
 Advance the utility relocation work.
 Often advancing utility work requires more than
clearing and grubbing. Upfront work such as
significant rough grading, etc.

Approach…..
 Utility Construction to follow the highway
construction staging.
 Utility Construction often drives the highway
construction staging & sequencing.

Approach…..
 A utility conflict is identified when there is a
“direct hit”
 Very often “Indirect” utility conflicts are the
cause of costly and time consuming construction
field problem….sub-grade compaction, temporary
sheeting, construction vibrations, unstable cast iron utility,
utility staging, etc.

identifies specific
requirements of utility
relocation/protection activities
with the overall project
construction staging and
construction activities.

The Utility Constraints Map
is a contract document that
provides information
regarding critical utility
infrastructure within the
construction work limits.

Utility Risk Mitigation - “Take-Away”
Frequent Statement…..
 Utility Companies are delaying the project.
Reality Often is …..
 An unanticipated “utility related” field issue ,not
properly identified during design, is the cause of
project delay.

Utility Risk Management
Effective Utility Risk Management
starts with an appropriate level
Subsurface Utility Engineering
(SUE) Investigation.
The presentation to follow will dig
deeper into the use and benefits
of SUE.

Subsurface Utility
Engineering
ACEC NJDOT FHWA Design Summit
May 18, 2016

“…is a professional service and branch of engineering
that involves…
• managing certain risks associated with utility
mapping at appropriate quality levels,
• utility coordination,
• utility relocation design and coordination,
• utility condition assessment,
• communication of utility data to concerned parties,
• utility relocation cost estimates,
• implementation of utility accommodation policies, and utility design.”
What is Subsurface Utility Engineering?

Quality Level D – Information derived from existing utility records
or oral recollections.
Quality Level C – Surveying visible above-ground utility surface
features such as valves, pole drops, meter pits, and using
professional judgment in correlating this information to QLD
information.
Quality Level B –Using surface geophysical methods to
determine the existence and approximate horizontal position of
subsurface utilities.
Quality Level A – Using minimally intrusive excavation equipment
at a specific point to obtain vertical information along with type,
condition, size and material.
Depiction of Utilities as Quality Levels

Visual Evidence of Subsurface Utilities

Why use Subsurface Utility Engineering?
It’s been proven Cost Effective…..
COST SAVINGS ON HIGHWAY PROJECTS UTILIZING SUBSURFACE
UTILITY ENGINEERING
Prepared by Purdue University Department of Building Construction
Management, December 1999 Prepared for the Federal Highway
Administration, Washington, DC 20002 FHWA Contract Number
DTFH61-96-00090
The Pennsylvania Transportation Institute of the Pennsylvania State University
(PSU) conducted an in-depth benefit-cost analysis in 2007 of 10 SUE projects
executed by PennDOT Districts. The PSU research shows that, in comparison
with projects not utilizing SUE, the total cost savings of SUE projects may range
from 10% to 15% on a typical project.
“On January 10, 1996, a routine capital improvement project
caused damage to an electric cable at Newark International
Airport, resulting in more than $1 billion of impacts, including
hundreds of cancelled and re-routed flights, disruption of
travel to tens of thousands of people, and complete closure of
the airport for more than 24 hours. “
ACRP – Airport Cooperative Research Program Synthesis 34,
March 2012
THE ROOT CAUSES OF DELAYS IN HIGHWAY CONSTRUCTION
• The purpose of the survey was to obtain input from working professionals
concerning the most frequent causes of construction delay and delay
avoidance measures.
• Utilities and Utility Related Activities were #1 and #2

Benefits
“Since 1991, FHWA has been encouraging
the use of SUE on Federal-aid and direct
Federal highway projects as an integral part
of preliminary engineering.”

The Final Word by
Federal Highway Administration
Using Subsurface Utility Engineering on Design Projects will:
• Reduce unforeseen utility conflicts and relocations
• Reduce claims and change orders
• Reduce delays due to utility cuts
• Lower project bids
• Reduce redesign costs
• Reduce project delays due to utility relocations

What’s is Advanced Utility
Relocations?
• Utility relocation before
construction
• Saves time & money

Why Do Advanced Utility Relocations?
■ Convenience to motoring public
■ Time Saving
■ Systematically Beneficial (Makes Sense)
■ Avoid Conflict (Utility Company & Contractor)
■ Avoid potential delay claims

■ Design
– Advanced Utility relocations decided early
■ Pre- Construction
– No Contractor on-board
– NJDOT Resident assigned to the project
■ Coordination
– Monthly or bi-weekly meetings should be held

Reasons not to do Advanced

■ Does not save money
■ Too Disruptive to public/community
■ Highly sensitive area
■ Utility Company Seasonal
