The primary objective behind determining the new specifications was to facilitate the purchase of bitumen products of better quality because these specifications will clearly describe the product for potential buyers. The new specifications also guarantee the proper performance of bitumen in coating. Climatic conditions are important factors in the efficiency of coating, but limited research has been conducted on this issue due to limited time and quite similar weather conditions. Moreover, they would not be precise if the loading factor is not taken into consideration. The producers all around the world, has been started to produce this type of bitumen which WLPC is a prominent in this regard. Having installed SHRP systems, White Lighthouse Petroleum Company is capable of selling bitumen to its customers based on PG method. It worth to remind that in the past, penetration was used as a factor for bitumen grading. In performance grade, the focus is on the mechanical specification of bitumen while in penetration grade, experimental parameters are involved. In the G.C.C countries, pen grade is more common, but in some cases, PG has better be used for a better performance. Today, a PG is defined for polymer modified bitumen and pure bitumen based on environmental conditions and temperature. A wider PG range means higher resistance and more favorable specifications. White Lighthouse Petroleum Company has the capacity to supply all these grades. This company first conducted climate zoning in the GCC countries to specify the appropriate bitumen for different geographical zones.
