That project had first been awarded to East-International Group Incorporated under the regime of former President Ellen Johnson Sirleaf, but it came to a standstill 2017.However the Ministry of Public Works captured the incomplete Gbarnga Broad Street rigid pavement
construction project under the Public Sector Investment Program which highlights road connectivity under the pro-poor agenda, with Sidani Group Holding becoming the new contractor.
To study the impact of the projected temperatures and precipitation on the pavement, FHWA considered both flexible and rigid pavement
He said that rigid pavement
of BRT corridor on Reach-III was nearly 97 per cent complete and work on the Tehkal overhead section would also be complete by May 30.
Ikpeazu has recorded in this direction is the construction of some of these roads with the cement technology, which is also known as the'Rigid Pavement
This work investigates dynamic response of a rigid pavement
resting on an inertial soil.
It covers soils; aggregates; bitumen, bituminous binders, and anti-stripping agents; laboratory tests and properties of bitumen and bitumen emulsion; hot and cold asphalts; the fundamental mechanical properties of asphalts and laboratory tests; the production, transportation, laying, and compaction of hot mix asphalts; quality control; layers of flexible pavements; methods determining stress and deflections; traffic and traffic assessment; flexible and rigid pavement
design methodologies; pavement maintenance and strengthening; pavement evaluation and measurement of functional and structural characteristics; and pavement management and recycling.
Polymer modified bitumen, crumb rubber modified bitumen, stone mastic asphalt technology, cellulose fibre technology by Forta Fl Fibres, rigid pavement
technology, composite pavement technology, geo-grid reinforcement of pavements.
For the rigid pavement
in almost all scenarios, the simulated checks are not satisfied.
Other topics include the traffic capacity of Alpen car tunnels, misalignment of dowel bars in rigid pavement
joints, tire noise prediction, and increasing the service life of porous asphalt with rejuvenators.
It includes papers and case studies on field evaluation studies; rehabilitation techniques; modeling and analysis techniques; airfield and highway flexible rigid pavement
design; pavement evaluation--for example, the utilization of a falling weight deflectometer, roughness measurements, and ground penetration radar; subgrade stabilization techniques; pavement material design and characterization; pavement management systems; construction approaches and quality control and assurance; and field instrumentation.
