Abstract Communications technologies and e-commerce have profound effects on travel behavior, including shopping trips. Such changes are, in turn, transforming operations associated with the delivery of goods and services, and consequently, the use of transportation infrastructure, including residential roads. As e-commerce continues to increase, including the spike from pandemic-era lockdowns, an effect of the growth of home deliveries is the potential impact on pavement performance from the increased number and weight of delivery vehicles. Delivery vehicles are heavier than personal vehicles, and thus they have an outsized impact on pavement wear, especially in the case of residential streets designed for limited traffic volumes. A method of accounting for the increased heavier traffic is presented as slightly changing the pavement design such that the maintenance schedule of these roads remains the same. A doubling of the number of delivery vehicles leads to a shorter useful life of the pavement, and a corresponding increase in the surface thickness of the pavement that allows for the maintenance schedule to remain unchanged was determined to be 6.35 mm (0.25 in.). Each 6.35-mm (0.25-in.) increase in pavement surface thickness has a material cost increase of $10,874/km ($17,500/mi) of roadway for an average residential street. The analysis was repeated for the increased weight of electric delivery vehicles, and it was determined that an even greater pavement surface thickness is needed to keep the maintenance frequency consistent.
