Effect of Unstable Mix under Severe Traffic Loading on Performance of Asphalt Pavements in Tropical Climate

Table 1

Comparison of the design and actual growth rates.

Vehicle category	Number at design stage	Current number	Actual growth rate (%)	Predicted max. growth rate used for design (%)
Heavy trucks, 3-axle	123	N/A	8.3 (est.)	6.5
Medium/large single-unit trucks/lorries	198	440	8.3	6.5
Truck trailers and semitrailers	116	136	1.6	6.5

est. = estimated from next vehicle class, N/A = current vehicle classification combines this with the next upper category.
