325 INTRODUCTION Roller compacted-concrete-pavement (RC- C-P) is a solid and concrete should be zero in slump that is frequently utilized for pavements due to its quick building and economical nature (ACI 325, 2001). RC-C-P is frequently used in pavements, hydraulic structures, and materials for infrastructure (Fang et al., 1999; Atis, 2005; Chi and Huang, 2014). Although the materials used in RC-C-P exhibit the characteristics that are comparable to those of traditional concrete, the gradation of RC-C-P is comparable to that of hot mix-asphalt pavement. The volume of fine-aggregate (F-A) in the RC-C-P combina- tion is large, while the volume of water, coarse- aggregate (C-A), and binder is low (Lam et al., 2018). Additionally, the RC-C-P mixture is deter- mined and generated in a manner distinct from conventional-concrete-pavement (C-C-P) regard- ing placement strategy and design specifications (Harrington et al., 2010). RC-C-P is permitted as a pavement material, since it does not need dowel bars or steel reinforcement. This reduces the total cost of building the pavement. When compared to C-C-P, the RC-C-P can save up to 60% on costs (Pittman, 1994; Vahedifard et al., 2010). The primary factors influencing the characteristics of ordinary-portland-cement-concrete (O-P-C), such as density and (w/c) ratio is also taken into consideration while designing RC-C-P. Nonethe- less, the compaction characteristics of RC-C-P are basic factors in determining the appropriate load carrying capacity (Yerramala et al., 2014).

The objective of the research was to investigate the influence of various curing kinds and impact on the mechanical characteristics off RC-C-P. Three various curing techniques can be investigated, compared to lab-normal curing. The liquid membrane-forming compound (Sika Antisol WB) is by spraying to the surface of samples after 2-hour casting and then spraying the sides of the sample following mold extraction. Water is sprayed twice a day (8:30 a.m. and 2:30 p.m.) for three-days and also the damp burlap curing continues three-days. The best curing technique can be recommended is liquid membrane-forming compound technique, since the improvement of compressive strength results up to (12.80, 11.26 and 11.96)% at 7, 28 and 90 days, respectively, compared to lab-normal cur- ing results. While the compressive strength results reduced by (2.37, 3.64 and 4.29)% at 7, 28 and 90 days, re- spectively, using the damp burlap curing technique compared to lab-normal curing results, it should be taken into consideration that it is still within ACI recommendation (not less than 28 MPa). Finally, the spray-water curing technique needs to be carefully employed in mix design, due to the reduction up to (9, 8.94 and 7.67)% at 7, 28 and 90 days, respectively, for compressive strength test, compared to lab-normal curing results. The results of tensile and flexural strength for RC-C-P with different curing using similar trends with compressive strength results for all curing techniques.
