Asphalt is a strong adhesive used for road paving, roofing tar, roll-roofing, roofing felt, shingles, pipe covering, floor tile, waterproofing, and many other products and processes. Asphalt is a dark brown or black substance derived from crude oil. It may be a solid, a semi-solid, or a liquid. As indicated by Specifications D and D, emulsified asphalts are classified by type (rapid medium or slow setting) and by grade within type (viscosity in the case of the rapid-setting type or characteristic of the residual asphalt in the case of the medium and slow-setting types).Selection for use of a particular type and grade is controlled by type of construction (whether an.

WAPA takes pride in presenting this Asphalt Pave-ment Design Guide and will be happy to provide read-ers with additional information. Acknowledgments This guide builds on the Asphalt Pavement Design.

asphalts such as Gilsonite—a hard asphalt, and rock asphalt—impreg nated sandstone and limestone, have been employed for many purposes. The first use of asphalt as a paving material in this country was in Newark, New Jersey, about 90 years ago. Some six years later () additional work was done in Washington, D. C. After this. You may be most familiar with modified asphalt for paving, but modified asphalt has been used for roofing applications since the s. Asphalt is a cost-effective material for construction and waterproofing, but roofing products are subjected to wide and rapid temperature swings – even more so than paving.

Sulphur extended asphalt (SEA). The chemistry of asphalts at the molecular and intermolecular levels may help explain the variation of performance characteristics. There are over tens of thousand of different molecular variations that may be present in asphalts and having to measure the properties would be an impractical task.
Title: Guide to the Characteristics, Performance and Selection of Paving Asphalts. Publication code: PERFPAV. This publication documents a set of procedures, using climatic conditions and anticipated traffic levels, for the selection of asphalts for any paving project in Canada.
The methods supplement the Canadian General Standards Board (CGSB. characteristics of the asp halt to be a djusted by an app ropria te selection of co mponent asphalts.

Selection of an aggregate material for use in an asphalt pavement depends on the availability, cost, and quality of the material, as well as the type of construction for which it is intended. To determine if an aggregate material is suitable for use in asphalt construction, it should be evaluated in terms of the following properties.

Petaluma, CA and James R. Lundy Department of Civil Engineering Oregon State University. Whether or not it is used to pave a busy highway, waterproof a rooftop or smooth out an airport runway, Asphalt Materials Science and Technology acquaints engineers with the issues and technologies surrounding the proper selection and uses of asphalts.
With this book in hand, researchers and engineering will find a valuable guide to the. James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, Asphalt Emulsion.
Asphalt emulsion (emulsified asphalt), like cutback asphalt, is also designated as a liquid asphalt to distinguish this product from the typical semisolid to solid asphalt binders. It is a mixture of two normally immiscible components (asphalt and water) and an emulsifying agent (usually soap).
asphalt. Asphalts are known to be comprised of molecular species that vary widely in polarity and molecular weight.
The major objective of this portion of the work is to explain behavioral characteristics of asphalts in terms of chemistry. Polarity is a very major contributor to the performance characteristics.
Polar materials tend to associate. Information used to develop the process should reflect documented historical performance and cost records. The AASHTO Guide for the Design of Pavement Structures, published by the American Association of State Highway and Transportation Officials, outlines the considerations for pavement type selection in its Appendix B.
Description: The Asphalt Institute and PRI Asphalt Technologies have collaborated to develop this binder specification database. Available below (as downloadable pdf files) are individual documents for each of the 50 State highway agencies which summarize their respective asphalt binder specifications.
A binder identified as PG must meet performance criteria at an average 7 day maximum pavement temperature of 64°C and also at a minimum pavement temperature of −10°C.
Please note that maximum pavement temperature is typically higher than the air temperature by about 20°C since the dark color pavement absorbs the heat and retains it. Asphalt Paving Materials A Grade of emulsion other than FHMS-2h may be used where experience has shown that they give satisfactory performance B Diluted with water by the manufacturer.
C Diluted with water D Mixed in prime only. Table acts as a guide to uses of asphalt in cold mixes. Rubberized asphalt materials are the most common, and they're very cost effective. Cracksealing materials are performance graded, meaning that they're designed for specific temperature ranges.
Be sure the product is designed for, and has a history of performance in, the climate in which the project is located. Asphalt, black or brown petroleum-like material that has a consistency varying from viscous liquid to glassy solid.
It is obtained either as a residue from the distillation of petroleum or from natural deposits. The principal application of asphalt is in road surfacing, which may be done in a variety of ways. More than 50 percent of the California asphalts have difficulty complying with some of the PG specifications, because of their aging and temperature susceptibility characteristics.
Agencies and industry managed to build good performing roads, using these local asphalts in combination with the AR grading system and the Hveem mix design method.

For example, if cationic and anionic emulsified asphalts are mixed, the blend will break and separate into water and coagulated asphalt that will be difficult to remove.
