Field Validation for the Constructability of Exposed Aggregate Concrete Overlay

Table 1

Mixture proportions of exposed aggregate concrete overlay in mock-up and laboratory test.

Test type	Max. size of coarse aggregate (mm)	W/C (%)	S/a (%)	W (kg/m^3)	C (kg/m^3)	S (kg/m^3)	G (kg/m^3)
Mock-up test	10	45	27	189	440	430	1185
Laboratory test	10	45	30	189	420	495	1129

Note. W: water amount; C: cement amount; S: sand amount; G: gravel amount; a: sum of sand and gravel amounts.
