Asphalt mixture durability is defined as the ability of compacted asphalt concrete to maintain. its structural integrity throughout its expected service life when exposed to the damaging effects of the environment and traffic loading. Asphalt mixture durability is one of several factors affecting pavement durability, which is defined as the ability of a pavement to retain a satisfactory level of performance over its expected service life without major maintenance.
-What are the indicators used to measure the durability for asphalt mixtures?
- How can improve the durability of asphalt mixtures?
- How can measure the durability of asphalt mixtures?
There are several tests to measure the performance of the asphalt mixture, such as:
Dynamic creep
Moisture sensitivity
Fatigue beam
Indirect tensile strength
Rutting resistance
Resilient modulus
Dear
Temperature susceptibility, moisture damage, rutting resistance, low temperature cracking.
The long-term ability of asphalt to heat, weather, traffic, and time (due to oxidation and other environmental factors) is often defined as its durability. Therefore, the tests related to these cases; can indicate the durability of the asphalt mixture:
Temperature susceptibility (SHARP tests: and some traditional methods: PI), moisture damage (AASHTO T283 or Modified Lottman test), rutting resistance (AASHTO T324, ...), low temperature cracking (AASHTO TP105, ... ).
Please refer to its standard for more details.
