Burnt Papa Road Materials

Engineering Work (eg road, bridge, sawmill, dam)

Description

Between 1890 and 1925, road building in the "papa" mudstone areas of inland Taranaki and northern Wairarapa were severely constrained by the absence of durable roadstone.

Becasue of this suitable local mudstone was "burnt" using papa fired in temporary kilns. This produced produce a brick-like product which was broken and used as roadstone.

This material stopped being economical as motor transport became available and wood from forest clearing was no longer available. Burnt papa aggregate can still be seen in some unsealed road pavements. As such there is little evidence left. However, on some back roads burnt papa peices can be seen amongst the aggregate on the road.
