  One of the critical challenges in infrastructural constructions is designing
and planning operations and their related resources. The complex interlinked
composition of different factors and variables affecting resource productivity
has made simulation a powerful approach for operational planning. The
construction sector has recently seen a notable surge in applying various
simulation tools to enhance further the quality of projects planning,
particularly in large-scale infrastructure developments (e.g., highway
construction). Due to possible cost overruns in improper resource allocation,
optimizing the design and construction planning stages of megaprojects such as
massive pavement projects is essential. Recent studies aimed to build a
simulation-based strategy in construction designing and planning by combining
various simulation approaches (e.g., discrete-event simulation, system
dynamics, agent-based simulation, and hybrid simulation) to enhance the
planning phase. This paper introduces an evolving real-time hybrid simulation
technique regarding the projects intrinsic time-varying inputs and factors to
optimize the planning of Roller Compacted Concrete (RCC) pavement projects.
Several scenarios are investigated using various resource combinations to
achieve the best execution method for delivering concrete to the project. An
actual highway project case study validates the proposed model and its
application for future projects. This studys findings exhibit the proficiencies
of the simulation-based approach in resource planning of RCC pavement projects
within the time and cost constraints and their related regulations.
