Aug 21, 2017· Types of Asphalt Pavement The asphalt pavement is commonly divided into asphalt concrete pavement (), hot mix asphalt gravel pavement, penetrated asphalt pavement (), asphalt surface course, in terms of technology and usage Asphalt concrete pavem.
For asphalt cements graded by penetration at 77 ° F (25 ° C) (see Specification D 946) If needed, volume corrections for asphalt cements should be made according to Practice D 4311 TABLE 1 Requirements for Asphalt Cement, Viscosity Graded at 140 ° F (60 ° C) Note —Grading based on original asphalt.
It may be noted that penetration value is largely influenced by any inaccuracy with regards to size of the needle, weight placed on the needle and the test temperature; A grade of 40/50 bitumen means the penetration value is in the range 40 to 50 at standard test conditions; In hot climates, a lower penetration grade is preferred.
final performance grade, The asphalt with penetration grade 40-50 is equivalent to PG70-16 while that with penetration grade 60-70 is equivalent to PG64-16 KEY WO RDS : Asphalt cement, Superpave.
The base grade is generally used in corn stabilizing level The I-5 or top is commonly used for homeowners and business I-4 or Commercial top consist of a mixture of ¾ inches of stone and is used when added stability ans strength is needed for the asphalt These are the different grades of asphalt, but are there any different types of asphalt?.
" Asphalt cement" refers to asphalt that has been prepared for use in HMA and other paving applications This section uses the generic term, "asphalt binder", to represent the principal binding agent in HMA because "asphalt binder" includes asphalt cement as well as any material added to modify the original asphalt cement properti.

Cutback MC-800 is a medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or ‘cutter’ of medium volatility The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application After application the diluent evaporates, leaving asphalt cement to perform its function.
A grade of asphalt, say, PG 70-40 is a mix where the 70 stands for the asphalt temp max over the next seven days after layment of 70 degrees and the min experienced temp the grade should encounter.
In selecting a grade for a given use, it is desirable to select the grade containing the most asphalt, provided, of course, this grade meets other requirements To understand cutbacks the types must be discussed separately Rapid Curing Cutbacks—To produce this material an asphalt cement in the penetration range of 80 to 120 is combined with.
Therefore, although asphalt binders are of the same AC grade they may behave differently after construction Temperature susceptibility (the change in asphalt binder rheology with temperature) can be somewhat determined because viscosity is measured at three different temperatures (penetration only is measured at 25° C (77° F)).

Asphalt cement is an asphalt which has been specially refined as to quality and , The penetration test can be used to designate grades of asphalt cement, and to measure , Solubility Test Asphalt consists primarily of bitumens, which are high-molecular-weight hydrocarbons.
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.
