Increase the 2019 Asphalt Testing contract value by $63,795 for additional quality control testing in 2022.
To extend the contract completion date to October 31, 2022.

Justification:

Asphalt Testing is a critical part of the Paving Program. It verifies that all the technical specifications and
quality requirements are being achieved throughout the project. S.W. Cole has successfully been the testing firm
over the last several years and has shown that they have the experience and staff to fulfill the City’s testing
needs.

S.W. Cole will provide full time plant inspection, field density testing, concrete inspection, and laboratory
analysis. The plant inspection includes gradation analysis and binder content of the hot mix asphalt to ensure the
approved mix designs are being followed. The field density testing will be utilized on reclaimed roads to verify
that the contractor is achieving the required relative compaction of the base material. The concrete inspection
will confirm that the material delivered for ADA ramp work meets the required specifications. The laboratory
analysis will test the asphalt for compaction and the concrete for strength.

2022 Pavement Preservation Program

To approve the award of the construction contract for the 2022 Pavement
Preservation Program to Sealcoating, Inc. of Braintree, MA in an amount of
$383,928.50. Funding through Department: 160 Admin/Engineering; Fund: Bond;
Activity: Paving.

2022 Pavement Preservation Map and Preservation Street List by Ward

The formation of cracks in roadways is inevitable, and once present they will evolve
as the asphalt pavement ages, oxidizes and deteriorates. To slow the rate at which
these distresses form, we are seeking to apply crack sealant to approximately 16.5
miles of City streets, over cracked sections of pavement to waterproof the asphalt
surface to protect underlying layers. This treatment is a routine maintenance
application proven to extend an asphalt pavement’s service life for 1-3 years and
delay the need for more extensive and costly treatments.

We are also proposing to apply asphalt rejuvenators/fog sealant to newer pavement
surfaces by applying this treatment to approximately 5 miles of Arterial and
Collector roadways. This product provides a cost-effective solution to penetrate the
top 3/8 of a roadway’s surface, soften the asphalt binder and improve cohesion
while also slowing the propagation of cracks. Through this process, oxidizing
pavement is revitalized and the overall loss of fines and aggregates is reduced. This
treatment extends the service life of asphalt pavement for up to three years with
each application.

The above work was advertised for bids and Sealcoating, Inc. of Braintree, MA was
the sole bidder. They are a qualified provider of the services and performed similar
work for the City last year.

Purchase and installation of six overhead 360-degree vehicle detection cameras on
Main Street

To approve the purchase and installation of six traffic camera systems on Main
Street by Electric Light Company of Cape Neddick, Maine in the amount of
$161,580. Funding will be through: Department: 161 Streets; Funds: Prior Year
Escrow ($130,420), Account Category: 71 Equipment; Department 160
Admin/Engineering; Fund: Trusts (Amherst Street $14,580; Main Street $16,580);
Account Category: 71 Equipment.

The City has been replacing the underground loops form of vehicle detection with
overhead 360-degree detection cameras in recent years. The underground loops are
routinely damaged by construction activity, utility work, or general wear and tear.
Overhead camera based vehicle detection works well without being as susceptible
to damage. We propose to install six of these camera systems at the following
intersections along Main Street: Amherst/Concord Streets, Franklin/Canal Streets,
Factory/Temple Streets, Prospect Street, Otterson Street, and Lake Street.

The City advertised this work for bids and received a sole bid from the Electric
Light Company in the amount of $187,550. Subsequent to bidding, the City
negotiated with Electric Light Company to modify contract scope and terms to
reduce cost without compromising the overall effectiveness of the camera systems.
