Polyroad Recommended Laboratory Testing
-
 Plasticity Index - may need to pre-treat
material if P.I. is consistently and well above 20.
- Grading - % fines passing 2.36mm to be at least equal to DGB20/FCR
specifications i.e. 35 to 55% passing.
- Capillary Rise and Swell - best if compared against parent material,
and parent material with lime.
- CBE - best if compared against parent material, and parent material
with lime (soaked and unsoaked).
Polyroad DPP is not suitable where:
- The pavement material is a sized graded macadam style pavement, i.e.
lack of fines resulting in voids within the granular matrix.
- Single sized coarse sands.
