Ko nga taputapu whakamatautau modulus resilient pavement(Benkelman Beam)

Ko te tikanga kurupae Beckman he tikanga e tika ana mo te ine i te uara paheketanga rapa o te mata o te rori i raro i te uta pateko, te uta tere tino puhoi ranei, a he pai te whakaata i te kaha o te mata o te rori.

Awhe ine:

(1) He pai tenei tikanga mo te ine i te paheketanga o te reanga o nga momo rori me nga papaariki hei aromatawai i te kaha o te kawe, ka taea te whakamahi i roto i te hoahoa o nga hanganga papa.

(2) Ka taea te whakamahi i te uara whakahuri o te papa rori me te papa papaa ngawari e inehia ana e tenei tikanga mo te tuku me te whakaaetanga whakaotinga.

(3) Ko te hurihanga whakamuri o te papaahi i inehia e tenei tikanga ka taea e te tari whakahaere tiaki huarahi te whakatakoto mahere tiaki huarahi.

(4) Ko te paheketanga o te papa raima i runga i te paerewa paerewa o te 20 ℃.I te wa e whakamatautau ana i etahi atu pāmahana (i runga i te awhe o te 20±2 ℃), me whakatikahia te uara paheketanga o te papa raima me te matotoru neke atu i te 5cm ma te pāmahana.
