Bending or flexural tests are the most widely used methods for assessing the fatigue resistance of asphaltic materials. Four point bending is included in both CEN and AASHTO specifications. The specimen is a prismatic beam, which is subjected to sinusoidal loading in the controlled strain mode. In Europe the principal alternative is two-point bending using trapezoidal specimens, a test which was developed at LCPC in France.
Cooper Technology manufactures several machines for asphalt fatigue testing like Servo-Pneumatic Universal Testing Machine, Gyratory Compactor, Servo-Hydraulic Universal Testing Machine, Stand Alone Four Point Bending Machine, European Standard Roller Compactors - Steel Roller, European Large Roller Compactor.

Calculate gallons of asphalt cement in a ton of asphalt?
The answer is, it depends. Different types of bituminous cement concrete (asphalt hot mix) use different percentages of asphalt cement. In Virginia, base mixes use at least 4.4% asphalt, while surface mixes are up to about 6%. Liquid asphalt is a little heavier than water; it weighs about 9.4#/gallon (depending on the source and grade). Here's the math: Base mix 2000#/ton x 4.4%/9.4#/gal. = 9.36 gal/ton surface mix 2000#/ton x 6%/9.4#/gal. = 12.76 gal/ton hope this answers the question.
Why should aggregates be well graded?
Aggregates must be well graded in order not to have a gap that may cause a weak point and that is necessary for : 1-Asphalt mixes 2-concrete mixes 3-Road material.
What is the mixing ratio of cements and aggregates and water in M30 concrete?
from M30 onwards the mixes are designed. they dont have a const ration as in the case of mixes like M10, M15....,M25
How do you make good concrete mix design?
deign as per the codes or the design methods and go for the trail mixes.////

What rocks or minerals are in asphalt?
Really depends on the mix and the application. A basic asphalt mix is stone, sand, and AC oil. Something like, say, PADL78M will be 78M stone, screened sand, and AC oil. Some mixes might have lime fill, and/or mineral fill. It all really depends on whether you're talking about Type A, Type B, Type C, or Open Graded mixes.
