| dc.description | Abstract: The rigid pavement test section was constructed of portland cement concrete (PCC) and trafficked with a 360-kip 12-wheel assembly and a 166-kip twin-tandem assembly to evaluate the performance of keyed and doweled longitudinal construction joints in rigid airfield pavement under multiple-wheel heavy gear loadings (MWHGL) and to investigate the feasibility of strengthening existing keyed longitudinal joints. The findings from this investigation are as follows: (1.) The performance of keyed joints of rigid pavements on medium-strength (k = 200 - 400 pci) foundations was marginal; (2.) it is feasible to strengthen the keyed joints in existing rigid pavements that are founded on low- to medium-strength (k < 400 pci) materials and are in good condition if the airfield is scheduled for MWHGL aircraft traffic; (3.) keyed longitudinal construction joints in existing rigid pavements constructed on high-strength (k > 400 pci) or stabilized soil foundations will probably perform satisfactorily under MWHGL aircraft traffic; (4.) a sand-filter course beneath a pavement structure will be effective in minimizing subgrade pumping; (5.) a 6-in.-thick stabilized base course placed over a low-strength (k < 200 pci) subgrade is very effective in increasing the load-carrying capacity of a 10-in.-thick nonreinforced PCC pavement; and (6.) doweled longitudinal construction joints in rigid pavements constructed on low-, medium-, and high-strength subgrades (k < 200 to > 400 pci) performed satisfactorily under MWHGL traffic.
