(c) Asphalt concrete mixture of AC 14 will be used to construct the wearing course layer. The coarse aggregate, fine aggregate and filler are used as materials to produce the asphalt concrete mixture. The aggregate gradation will be blended to fulfill the gradation limit according to JKR standard specification as shown in Table Q1(c)(i). Based on this statement, conclude the result of sieve analysis test of blended aggregate as shown in Table Q1(c)(ii).
