Performance Evaluation of JPCP with Changes of Pavement Mix Design Using Pavement Management Data

Table 2

Summary of Comprehensive Plan to Improve Concrete Pavement Quality (2010).

Item	Detail
Introduction of spacing factor	(i) Add standard air void spacing factor to durability indexes (0.2 mm or less)
Change of concrete pavement mix design standard	(ii) Increase unit binder weight (326 ⟶ 350 kg/m^3, fly ash 20%)
	(iii) Adjust air voids content (4–6% ⟶ 5–7%)
	(iv) Strictly manage admixtures (air-entrained, water-reducing, etc.)
