Application of cover material
-
Mat test completed (Q711A - 1996)
-
Test 1:
-
Mass of canvas mat & aggregate - m1 (kg):
-
Mass of canvas mat - m2 (kg):
-
Area of mat - nearest 0.002m2 (m2):
-
Spread rate - R1 (kg/m2): R1 = (m1 - m2) / Area
-
Loose unit mass of aggregate - DI (t/m3):
-
Spread rate - R2 (m2/m3): R2 = (1000*DI) / R1
-
Test 2:
-
Mass of canvas mat & aggregate - m1 (kg):
-
Mass of canvas mat - m2 (kg):
-
Area of mat - nearest 0.002m2 (m2):
-
Spread rate - R1 (kg/m2): R1 = (m1 - m2) / Area
-
Loose unit mass of aggregate - DI (t/m3):
-
Spread rate - R2 (m2/m3): R2 = (1000*DI) / R1
-
Has the binder been covered as soon as possible after spraying?
-
Is the application rate uniform and adequate?
-
Is aggregate firmly embedded into the binder?
-
Type of rollers used:
-
Did rolling commence within the required time frame?<br><br>▶ No later than 5 minutes for PMB<br><br>▶ No later than 15 minutes for cutback bitumen
-
Was back rolling carried out for the required minimum timeframe?<br><br>▶ 1 hour per 1000m2 for roads with < 500 v/l/d<br><br>▶ 1 hour per 1500m2 for roads with > 500 v/l/d
-
Was sufficient sweeping to remove loose aggregate conducted?
-
Did the contractor monitor loose aggregate and undertake additional sweeping if rate is higher than:<br><br>▶ 20 particles per m2 for urban areas<br><br>▶ 30 particles per m2 for med - high traffic (> 250 v/l/d)<br><br>▶ 40 particles per m2 for low traffic (< 250 v/l/d)
-
Spray sheet received?
