How to Determine Quantities

Base = 116 cuyds; asphalt pavement mixture = 151 tons A note about measuring areas of roadways with curv When determining the area of a roadway with a curve it is important that the length be measured along the centerline of the road By doing this the area is simply the length of the arc along the centerline times the width.

Chapter 3 Pavement Patching and Repair

for compaction later A pavement saw makes a good tool for a fast, neat cut in pavement patching After the cut is made and the defective pavement and/or base material is removed, level and compact the base material This will make an adequate foundation for the new asphalt concrete material Surfacing materials (gravel base, crushed surfacing).

Why is Bitumen Used in Road Construction? Properties and

Advantages of Bituminous Road Construction Over Concrete Pavements 1 A smooth Ride Surface It does not make use of any joints; Hence provide a smooth surface to ride It also gives less sound emission when compared with concrete pavements The wear and tear are less in the bituminous pavement, thus maintaining the smoothness 2 Gradual Failure.

Asphalt Pavement Construction

At one time it was thought that a prime coat was an essential element of good pavement construction However, in recent years some engineers have eliminated the use of a prime, especially when asphalt layer(s) (surface and/or base) is 4 inches or more in thickness.

STANDARD CONSTRUCTION SPECIFICATIONS FOR ASPHALT

necessary to complete the construction of hot mix asphalt concrete pavement consisting of one or more courses on a previously prepared base, seal coat of asphalt cement and cover aggregate, and bituminous surface treatment in single or multiple cours Article 12 Applicable Standards.

To Prime or Not to Prime , That is the Question

Home Asphalt To Prime or Not to Prime , That is the Question , Prime is not glue ' causing the base to adhere to the pavement is not its purpose , Since asphalt pavement is laid smoother.

Equivalency Chart

Concrete and asphalt pavements are not only made of different materials, but they also carry traffic loads in entirely different ways This means that the thickness design procedures for concrete and asphalt pavements are also different The structural number concept has, however, been used to estimate concrete and asphalt pavement sections.

Appendix A Pavement Distress Types and Causes

Appendix A Pavement Distress Types and Causes This Appendix provides descriptions of the types and causes of the distresses that occur in asphalt, concrete, and asphalt-overlaid concrete pavements, and asphalt and concrete shoulders Many of the photos used in this Appendix are from the LTPPDistress Identification Manual1 Asphalt Pavement.

Chapter 5 Surface Treatments and Pavements

Chapter 5 Surface Treatments and Pavements 5-01 Cement Concrete Pavement Rehabilitation SS 5-011 Description Rehabilitation of Portland Cement Concrete Pavement is undertaken in order to repair damage to the roadway, extend the life of the pavement, prevent further damage to the pavement, and to provide a smoother ride to the traveling public.

Bases and Subbases for Concrete Pavement

Asphalt dense-graded base Asphalt-treated base Asphalt-treated open-graded drainage layer Stabilized bases are typically constructed using concrete or asphalt paving equipment that can achieve a smooth surface As such, the use of stabilized bases under a concrete pavement can contribute to achieving a high level of smoothness for concrete.

Pavement Manual: Treated Subgrade and Base Courses

Section 4: Treated Subgrade and Base Courses , , such as asphalt, cement, fly ash, or lime , application of materials with additives will minimize premature failures of the material and pavement structure Base and subgrade materials are treated with chemical additives to achieve one or more goals when available materials do not meet.

Asphalt Concrete Base (ACB)

Asphalt concrete base (ACB), also called asphalt treated base (ATB), is a dense-graded HMA with a larger nominal maximum aggregate size (1 inch) intended for use as a base course or binder course (see Figure 1) In addition to site paving benefits, ACB can be advantageous because it can provide: A waterproof barrier to prevent fines infiltration into the subgrade and pavement structure.

Differences Between Concrete and Asphalt Pavement

The major factor considered in the design of flexible pavements is the combined strength of the layers One further practical distinction between concrete pavement and asphalt pavement is that concrete pavement provides opportunities to reinforce, texture, color and otherwise enhance a pavement, that is not possible with asphalt.

Bituminous Surface Treatments

Jul 19, 2011· Bituminous surface treatments (BST) refer to a range of techniques that can be used to create a stand-alone drivable surface on a low volume road, or rehabilitate an existing pavement Usually, the term is used to describe a seal coat or chip seal, which is constructed by spraying a layer of emulsified asphalt, and placing a layer of aggregate on top BSTs can be applied directly to a base.

Asphalt concrete

Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, as well as the core of embankment dams It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted.

When is a Tack Coat Necessary?

A tack coat replaces the worn away asphalt and promotes bonding with the old pavement What is a “Tack Coat?” A tack coat is sprayed on the surface of an existing asphalt or concrete pavement by a distributor truck immediately prior to placing an overlay The goal is to achieve uniform coverage over the entire surface to be paved.
