1.3.5.Base Course
- Base courses are most typically constructed from durable
aggregates. The Material in this base course are crushed
igneous rock (granite, marble etc), limestone, soil aggregate - Use the High quality of Materials because this base
course are received by the high density of stresses.
In certain situations where high base stiffness is desired, base courses can be constructed using a variety of HMA mixes
Type of Base
1. Hot-rolled Asphalt
2. Water bound Macadam
3. Soil Stabilization
4. Base course or Soil Aggregate*
*in most case we use in Thailand
