Economic efficiency of road maintenance is an important topic in science and practice. Especially maintenance programs and their technical and economic efficiency is an important aspect.
A decisive parameter for systematic road maintenance is the possibility of prediction of deterioration processes, which depends on basic material or pavement properties (e.g. deformation, fatigue).
That is why established methods for useful life determination (based on fatigue considerations) and de-terioration processes (rutting) of asphalt pavements were applied for exemplary road sections. Further-more alternative scenarios were considered.
In terms of concrete pavement sections exiting methods were checked towards applicability for the de-termination of useful life. Newly developed methods (hazard functions) were applied exemplarily.
In case of an ASR deterioration of concrete pavements a systematic maintenance planning is impossible so far because the prediction of deterioration is hardly possible. Therefore different material tests (de-structive (non-destructive) were applied at ASR affected pavements. The determination of remaining use-ful life is not possible with that results anyway. That is why an empirical method using road condition da-ta (ZEB data) was developed.
Based on the described approaches of useful life prediction and other deterioration parameters, com-parative economic studies under consideration of different assumptions and scenarios were implement-ed in a simulative way using the software LCD2.
