2019 PAVEMENT
MANAGEMENT
PROGRAM
IMPROVES
ROADWAYS
In 2019 The Village’s Annual Pavement
Management Program extended the life
of approximately 19 of the Village’s total
224 roadway network lane miles. The
maintenance strategies consisted of
preservation treatments including
rejuvenator seal and cape seals as well as
rehabilitation treatments like hot mix
structural overlays. Work began in April
and will continue through October.
To achieve the outcomes of the
Pavement Management Program a
variety of maintenance strategies are
applied to sustain a high-quality
pavement network throughout the
Village that results in safe, smooth, and
visually appealing roadways. The specific
strategy selected for each street is
determined based on several factors
including: traffic volumes; the remaining
structural life of the pavement; and types
and severity of the distresses present. The
goal is to apply the right treatment, to
the right road at the right time.
Preservation treatments are cost effective
surface treatments that are placed on a
roadway surface early in its life cycle.
The goal of a preservation treatment is
to protect the asphalt surface from
oxidation caused by air, sun and water.
Oxidation leads to the pavement
becoming less flexible, which in turn
leads to cracking and degradation of the
asphalt surface. By applying a
preservation treatment early, the life of a
roadway is extended, and future
rehabilitation costs are minimized.
Preservation treatments were applied to
11.7 lane miles of roadway in 2019.
Rejuvinator Seal being applied
A cape seal was applied to the
Timberline Orchard subdivision off of
Dayton Street. This two-layer system is
performed on streets that are still in
relatively good condition. The treatment
provides a long lasting, asphalt rich seal
that results in a smooth final surface.
Ahead of the cape seal application, crack
sealing and minor patching is performed
to repair and seal these localized areas.
In the Dayton Farms, Greenwood
Gardens, Big Canon, Greenwood Acres
and Orchard Hills residential
subdivisions a rejuvenator seal was
applied. This application serves to renew
the asphalt binder on the surface of the
pavement, thus deterring oxidation and
cracking. This treatment was also
applied on Holly Street.
Asphalt overlay in The Preserve
Rejuvinator Seal after curing
Pavement rehabilitation is a more robust
maintenance strategy which consists of
major asphalt patching of structural
deficiencies, followed by removal and
replacement of the top few inches of the
roadway surface. This treatment is also
known as a mill and overlay.
Rehabilitation is performed later in the
life cycle of a roadway. Streets that
received a mill and overlay in 2019
include Syracuse Street (north of
Arapahoe Road), Willow Way (Orchard
Road to Fair Avenue), Boston Street
(south of Belleview Avenue), Prentice
Avenue (east of Monaco) as well as the
residential subdivisions of Preserve filing
3 and Greenwood Pines, comprising a
total of 7.6 lane miles.
