To resist rutting on the heaviest road in the North is a huge challenge for both the base layer and 2 PMB layers (PMB-I and PMB-III). Day or night, this road is always busy with container trucks & heavy trucks from Hai Phong Port to almost all industrial zones and northern provinces (Hai Duong, Hung Yen to Ha Noi, and all development provinces in the North, such as Bac Giang, Bac Ninh, and Vinh Phuc). The VIDIFI requires the highest quality of PMB for the trial junction for 1 year of validation before main route repair works begin. KBC Napthanic 60/70 with a high softening point is used to make high modulus asphalt base C25.
